'51 Flathad

Hi Folks:
I'm looking for a bit of info on my '51 flathead. I am in the midst of rebuilding the engine, as part of the restoration of a '51 F1 Pickup. Does anyone know the correct sparkplugs for this engine? Also,I am trying to find out what the original color of the engine was.
Thanks for your help

The reason for not posting Tech questions in regionbal chapters.
It is because if another user comes on the site searching for the same information, why would he bother checking in a District Chapter as opposed to a Tech forum like the Flathead related forum ? ?
